ARRANGMENT OF VALVES FOR PUMPS, 8:.0.

SPECIFICATION bmning part 0f Letters Patent N0. 690,879, dated. January '7, 1902.

Application led April 12,1901. Serial No.155,537. (No model.)

To a/ZZ wiz/0m t may concern:

Be it known that I, FREDERICK W. ROGLER, engineer, a citizen of the United States of America, residing at V Lipt Krt No. 1, in the city of Budapest, Empire of Austria-Hungary, have invented certain new and useful Improvements in the Arrangement of Valves for Pumps, Compressors, Blowing-Machines, and the Like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved arrangement of automatic valves for pumps, compressors, blowing-machines, and the like. If such machines have to be driven at a high speed, it is difficult to obtain the necessary fluid-passage area at the admission and exhaust valves without unduly increasing the dimensions of the valve-chest.

The object of this invention is to so arrange the automatic admission and exhaust valves of pumps, compressors, blowing-machines, and the like'that on the one hand the space occupied by such valves and valve-casings is reduced to a minimum and that on the other hand the valves are readily accessible- A further object of this invention is to so arrange the valves and the valve-casings that they can be used for the admission or for the exhaust of the iiuid without requiring any change Whatever; and still another object of this invention is to so construct the valves and valve-casings that they can be readily manufactured in large quantities and at a low price.

This invention is not limited to the use of any particular formror construction of automatic valves; but annular valves supported by elastic tangential links, such as described in the United States Patent No. 604,326, are particularly suitable for carrying into practice the present invention.

In the accompanying drawings, Figure` l is an elevation and partly a vertical section of a blowing-machine provided with the present valve arrangement. Fig. 2 is a side elevation and partly a longitudinal section thereof. Fig. 3 is a longitudinal section of the valvecasing and valves, taken on the line 8 3 of showing the valve proper in plan with one of the disks broken away; and Fig. 6 is a transverse section taken on the line 6 6 of Figs. 3 and 5 looking in the direction of the arrows.

a is the cylinder, b is the piston, and c is the piston-rod, of a double-acting blowing-machine. The air is admitted to the cylinder through the suction-valve chests cZ and e, and the air under pressure is forced out through the exhaust-valve chests fg, the suction-valve chests being connected with the cylinder by channels h, while channels t' connect the cylinder with the exhaust-valve chests.

The construction of the suction and exhaust valves and valve-casings are or may be identical. Each of these valves comprises a series of valve-seats lc and a series of valve stops or disks Z, alternating with the seats, both seats and stops being carried by a common central spindle m. Between each seat and the adjacent valve-stop an automatic valve q is located, such valve being preferably supported by spring-links q', connected at one 'end to the valve q and at their other ends to the stop Z and constructed as described in the United States Patent No. 604,326, above referred to.

Preferably the valve-seats are hollow and double-faced-that is to say, each of the faces of the valve-seat bodies 7o' constitutes a seat for a valve q. Similarly the valve-stops Z are preferably double-faced, so that each of the stops carries two valves q, one on each of its faces, as shown. The valve-seats and valvestops Zz Z are held tightly against each otherv .1 by heads s, held on the spindle min any suit able manner-for instance, by nuts--suchy heads serving also as stops for the outermost valves q, as shown.

In the construction shown the hollow valve- `seats 7c are provided with ports or slots 1o on with the compartment-space into which theyV are placed.

The valve-casing for the valve above described consists, substantially, of a hollow cylinder c, of suitable cross-section, divided by transverse partitions w into alternating compartments o and u, provided with lateral openings or slots o and u' for permitting fluid to enter into or escape from such compartment-s, respectively. The said partitions w are provided with central openings w, into which the valve-seats 7o exactly iit, and the distance between adjacent partitions w, forming the walls of a compartment 0, is such that when a valve-seat is placed into such compartment, as shown, it completely closes the central opening in both partitions. On the other hand, the distance between two adjacent partitions w, forming the walls ofa compartment u, is such as to provide sufficient place for a valve-stop Z and valve or valves q. The number of compartments o of the valve-casingis of course equal to the number of valve-seats in the valve above described, so that if the 'valve is inserted into the valve-casing and locked in position in any suitable manner all the compartments 0 receive valve-seats, while the compartments u receive the valve-stopsZ and valves q, as shown in Figs. 3 and 5.

When the valve is mounted in the valve# casing, as described, the whole may be secured to the compressor, pump, or blowingmachine in any preferred manner at the proper place and will be ready for use.

It is only necessary to so arrange the valve the operation of the blowing-machine, pump, or compressor is higher communicates with the compartments o, while the other of these two spaces, in which the duid pressure is lower, communicates with the compartments u. Thus, as shown in the drawings, the compartments u of the suction-valve e communicate through channels h with the interior of the cylinder, while the compartments 0 com- 1 i they combination with a series of disks having f recesses in their perpheries, and ports openi ing through their sides into said recesses, of

municate with the atmosphere, as at n, while in the delivery-valve g the compartments ocommunicate with the interior of the cylinder by channel t', whereas the compartments u communicate with the conduit or collector for the air under pressure. It will be seen that during the suction-stroke the valves q of e will open to admit air into the cylinder, while during the pressure-stroke the valves q of g will open to permit the air under pres- 1y the combination with a spindle, disks mountsure to escape into the conduit or collector. Therefore the valve as an entiretyviz. the

casing o, with the seats Za, stops Z, and valves` q secured therein,as described-may be. manufactured and brought on the market independently of the body of the pump, compres. sor, blowing-machine, or the like and may then be secured to the latter as may bedesired.

The casing fu, together with the valves,- valve-seats, and valve` stops, as above de.-l scribed,constitutes what may be called afmiultiple automatic valve, which may be readily brought into position and removed therefrom as an enirety and which may be readily taken to pieces by simply removing the head or heads s and the spindle m. The constituent parts of the multiple valve-the valves proper, the valve-seats,and the valve-stops--being interchangeable, respectively, any damage may be repaired by simply substituting for the damaged part a fresh one. Moreover, the number of constituent parts of dierent forms or construction being small, such multiple valves may be manufactured in large quantities and at a low cost.

Obviously the fluid passage area at the valves q is comparatively very large, even if the stroke of the individual valves q is small.

It is obvious that the valve-seats Zo and stops Z, instead of being double-faced, as shown, may be single-facedthat is to say, may have a valve-.port or a valve, respectively, on one of their faces only.

It will be seen that the construction of the valves proper, q, the valve-seats Za, and the 1 stops Z, as well as that of the casings c, may be varied within wide limits without depart- 'ing from the essence of this invention and `that the number of valves proper in each i multiple valve and also theA number and po'- sition of such multiple valves on the cylinder.

or cylinders of the compressor, pump, or blow- J ing-machine may be chosen at will, that of thek two spaces to be connected by thev valve the one in which the fluid-pressure in I claim-- l.
